现代科学认为“水——土壤——植物——大气”是一个宏观综合体,即在生态系统中进行能量、热量的转换。而水分的合理利用和管理是充分利用水资源提高作物产量的一项重要内容。在水稻生产中,不适当的灌溉方法及不利的水环境(如渍害稻田),会使水稻得不到适宜的生长生态环境,引起生态环境失调,造成水稻减产。因此,这就涉及到水与水稻生态环境关系的问题,即水稻的环境水利问题。本文试通过叙述水与水稻生态环境的主要关系问题,进一步讨论利用供水与排水方式,不仅要满足水稻生长各阶段对水分的要 Modern science holds that “water - soil - plant - atmosphere” is a macro complex, that is, energy and heat are converted in the ecosystem. The rational use and management of water is an important part of making full use of water resources to increase crop yield. In rice production, improper irrigation methods and unfavorable water environment (such as paddy rice fields) can make rice not get suitable growth and ecological environment, causing the ecological environment imbalance, resulting in reduced yield of rice. Therefore, this involves the relationship between water and rice ecological environment, that is, rice’s environmental water issues. This paper attempts to describe the main relationship between water and rice ecological environment by further discussing the use of water supply and drainage, not only to meet the various stages of rice growth to water
